I am getting back into cycling since before I needed to shave.
Actually the last bike I rode was a motorcycle. The "brain bucket" I used to wear (by law) needed a DOT sticker on it to show that it was certified. I am surprised that bicycle helmets don't need these.
The Giro I have is made out of styrofoam (or something like it) covered with a thin plastic shell which isn't even glued to the foam; it's held on by a thin strip of tape. If I took off the shell and epoxied it to the foam, I wonder if it would provide better protection, or should I shop for a better helmet?
